Assigning a Viewer Light Shader

As supplied, the Katana Viewer supports a single type of OpenGL spotlight, which corresponds to the Katana Spotlight final render light. For lights of types other than Katana Spotlight to display in the Viewer, they must have a Viewer light shader assigned.

It is this Viewer light shader, not a renderer's shader, that the Viewer displays when in Shaded (raw) or Shaded (filmlook) modes. For example, create a primitive, and assign it a material that also has a Viewer material shader. Create a light, then observe the Viewer output in Shaded (raw) mode.

1.

Open the recipe created in Assigning a Viewer Material Shader.

2.

Select the GafferThree node, then the light you created earlier, and go to its Material tab.

3.

Click Add Shader and select light from the dropdown menu.

4.

Select one of the following lights as the shader type: KatanaBasicPointlight, KatanaBasicSpotlight, or KatanaSpotlight.

5.

Change the Viewer to Options > Shaded (raw) mode.

The Viewer shows the Viewer light, and changes to the Viewer light update in the Viewer.
